| `vae_dtype`      | STRING       | Yes      | Data type for VAE ("bfloat16", "float16", "float32") - advanced |

### Outputs

| Parameter | Type  | Description                                                 |
|-----------|-------|-------------------------------------------------------------|
| `MODEL`   | MODEL | Loaded model with applied LoRAs and optional merge          |
| `CLIP`    | CLIP  | Combined CLIP-L and CLIP-G text encoders with applied LoRAs |
| `VAE`     | VAE   | Loaded VAE                                                  |

### Usage

Extended version of the SDXL loader with support for up to 4 LoRAs and additional VAE configuration options. Load all
model components, optionally merge checkpoints, apply LoRAs sequentially, and configure device/dtype settings for CLIP
and VAE. LoRAs are cached for efficiency.
